If a quantum measurement is, in principle irreversible, and is the result of a decoherence process which in principle is reversible (since it's unitary), is this not a contradictory position? This seems to be your position IIUC. CMIIAW. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
